This is my first post on this forum so moderators please move it to the most appropriate thread category, if this isn't it. Thank you.

I shoot with an Argus C3 brick 7 speed 1/10-300 F3.5-16 Coupled Focus.

I understand the Sunny 16 rule, and want to know if there is a way of making some kind of reference chart. I pulled out my digital camera to do metering (Olympus PEN) and using basic arithmetic, I came up with this chart.

Assuming ISO 200 for all.
Br't Sun - F16 - 1/200 sec F11 - 1/400 sec ETC
Sun - F11 - 1/200 sec F16 - 1/100 sec
Hazy Sun - F8 - 1/200 sec F16 - 1/50 sec
ETC

I want to know if there is some other formula.

Or was that not what you were looking for.

Welcome and pardon my humor. You have it pretty good there. Using the Pen as a guide is a good start. A better one would be to find a light meter. You can find an old Sekonic. Even if the photo cell does not work the slide rule dial can help get you a custom to shutter/aperture combinations.

Your table is good. The "shadow" information at this link is helpful too:

It used to be that when you bought a roll of film, it included a chart just like this.

My first new 35mm camera (a Retina S1) had one buit right in, instead of a meter.

Thanks

I will use the chart as an aperture guide to get it more accurate, and post the finished product.
